Question

Match the phenomenon in Column I with the Scientist who suggested it in Column II

Column I (Phenomenon)	Column II (Scientist)
(A) Linkage	(I) Sutton and Boveri
(B) Chromosomes	(II) Gregor John Mendel
(C) Chromosomal Theory of Inheritance	(III) T. H. Morgan
(D) Principles of Heredity	(IV) W. Waldeyer

• A. A - IV, B - III, C - II, D - I
• B. A - III, B - II, C - IV, D - I
• C. A - II, B - III, C - IV, D - I
• D. A - III, B - IV, C - I, D - II

Hint:

Recall who named chromosomes, who proposed the chromosomal theory, who worked on linkage and who framed the basic laws of heredity.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
Each genetic phenomenon is linked to the scientist who proposed or named it.

Step 2: Match the pairs
Linkage was reported by T. H. Morgan from Drosophila crosses (A - III). The term chromosome was introduced by W. Waldeyer (B - IV).

Step 3: Match the rest
The chromosomal theory of inheritance was put forward by Sutton and Boveri (C - I). The principles of heredity were framed by Gregor John Mendel (D - II).

Step 4: Conclusion
The correct combination is A - III, B - IV, C - I, D - II.

Final Answer:
The correct matching is A - III, B - IV, C - I, D - II. \[ \boxed{\text{(D) }\text{A - III, B - IV, C - I, D - II}} \]
